Chapter 4. How To Conﬁgure SIP

Remote SIP Connectivity

If you have remote SIP clients behind other NAT boxes, you need to activate Remote NAT

Traversal.

Interoperability

You need to set the URI Encoding settings on the Interoperability page to "Use shorter,

encrypted URIs".

You need to enter the public IP that corresponds to the Telecommuting Module under Pub-

lic IP address for NATed Telecommuting Module. This will make the Telecommuting

Module able to rewrite outgoing SIP packets properly.

Save/Load Conﬁguration

Finally, go to the Save/Load Conﬁguration page under Administration and apply the new

settings by pressing Apply conﬁguration.
